Definitions

  • the invention relates to an endoprosthesis for an acetabular cup, which has a self-tapping thread on its outer jacket and forms at least essentially one plane perpendicular to the socket axis in the pole area.
  • the outer jacket When inserting, driving in or screwing the pans into the pelvic bones, the outer jacket exerts, among other things, a compressive force on the bone, the line of action of which is perpendicular to its surface. If one divides this force c into a component a perpendicular and a component b parallel to the socket axis, the ratio of these components is constant in the shape of a truncated cone, whereas it changes very quickly in the spherical socket between equatorial and pole-near "widths" in the sense that from the equator to the pole, the component perpendicular to the pan axis decreases relatively quickly and the parallel component increases.
  • the invention has for its object to provide a pan of the type mentioned, which combines the advantages of the two forms described, but avoids the disadvantages.
  • This object is achieved with the invention in that the outer surface of the socket body and / or the envelope of the screw thread form the branch of a hyperbola in cross-section, one leg of the hyperload running in the plane on the pole side, while the other the surface line of the socket body or is the envelope for the thread, and the axis of symmetry through the apex of the hyperbola also forms an angle between 48 ° and 58 ° with the equatorial plane of the socket.
  • the socket body has four grooves distributed on its equatorial edge, which run at an angle to surface lines parallel to the socket axis.
  • the slope of the groove ensures a secure fixation of the prosthesis on the screw-in instrument.
  • the single figure shows, using the example of an acetabular cup consisting of a shell and a shell body, a view of the new prosthesis, partly in section.
  • the actual socket shell 1, which does not contain a joint head, is located in an inner shell body 2 made of plastic, for example made of polyethylene.
  • Their axis, which coincides with the rotational symmetry or pan axis, is designated by 3.
  • the shell body 2 is pressed or shrunk into a metal sleeve 4, for example made of titanium or titanium alloy, a "negative", i.e. a cone 5 widening towards the pole of the pan shell 1 on the shell body 2 and on the shell 4 results in an additional hold.
  • a metal sleeve 4 for example made of titanium or titanium alloy
  • the outer jacket 6 of the sheath 4 is provided with a self-tapping thread 7, which can be more or, as shown, single-start.
  • both the outer surface 8 of the outer jacket 6 and the casing 9 for the thread 7 form a hyperload in cross section, in which one leg extends in the plane on the pole side extending perpendicular to the socket axis 3.
  • This is partially structured by grooves 10 which are concentric with the axis 3 and which promote the growth of tissue.
  • the axes of symmetry 11 or 12 form an angle ⁇ of approximately 55 ° or 51 ° with the equatorial plane of the pan in the present example.
  • grooves 13 are evenly distributed over the circumference, the longitudinal axes of which form an angle ⁇ with the surface lines of the shell 4 running parallel to the pan axis.
  • the grooves 13 serve for the engagement of a screwing instrument, not shown, the incline position of their longitudinal axes ensures a secure fixation between the two.
  • blind bores 14 are therefore provided, which are matched to the grooves 13 and their incline in such a way that the screw-in instrument fixed to the sleeve 4 additionally engages in the bore 14.
  • the invention is not tied to the two-part embodiment of a prosthesis for an acetabular cup shown and described. It can also be used in the same way for constructions in which the prosthesis consists of a socket body, e.g. made of metal, which contains both the pan shell and the outer structure.
